UNITED STATES PATENT CLARENCE L. BISBEE, OF BROOKLYN ,NEV YORK.

GAS-STOV'E.

SPECIFICATION forming part. ol' Letters Patent No. 393,094, dated November 20, 1888.

Application tiled February D, 1F88. Serial No. 263,644.

To aZZ whom t may concern:

` Be it. known that I, CLARENCE L. BisBEE, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Gas-Stove, of which the following is a full, clear, and exact description.

The object of my invention is to .provide a verycheap and averypractical gas-stove,which may be regulated to burn practically a small flow as well as a large or full ow of gas; and to these ends the invention consists of the construction and combination, as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical sectional elevation of my new and improved gas-burner. Fig. 2 is a plan view of the same. Fig. 3 is a detached plan view of the adjustable device for regulating a small flow of gas. Fig. 4 is a modification of the regulator, and Fig. 5 is a perspective view of the regulator shown in Fig. 3.

A represents the cylindrical chamber, reduced in size at its lower end, as shown at a, to fit upon the gas-jet tube B. Openings b Z1 are formed in the chamber A to admit air' to said chamber, and at the upper end of said chamber is formed the small opening c, from which a jet of flame burns when the gas is turned on and lighted. Cast with the chamber A as one casting are the hollow arms G C, the surrounding flange D, and the upright pieces E', which rise from the upper edge of the flange D. In the upper and lower walls of the hollow arms C C are the corresponding passages, d d', formed in casting, so that the whole stove is made in one piece or casting, and is therefore very cheap.

rl`he hollow arms C communicate with the interior of the chamber A, as indicated in Fig. 1, so that when the gas is turned on and lighted it will ilow to the ends of the arms C and burn at all of the upper openings, d, in the said arms. The air to support combustion at the upper openings, d, is supplied through the lower openings, d', so that an intense heat is produced and back-lighting prevented.

W'hen the is turned low and a small amount of heat is required, I employ the regu- This is formed with a base or lator E, Fig. 5.

circular portion, E2, having upwardly-projecting platesf, as many in number as are arms C. These plates are of such a width as to enable them to enter the apertures d din the arms G, and they are bent slightly outward, so as to enter the said' apertures d d nearest the chamber A. They are also slightly curved inward, so that their upper ends, which are slightly concaved to snugly fit the apertures d d', will impinge against the inner edges of the upper apertures, d, leaving a space, di, between the said plates and the inner edges of the lower apertures, as clearly shown at the right in Fig. 1. The object ofthe platesf is to impede the ilow of gas so it will not reach to the outer ends of the arms (l. In the practical application of the regulator E the same is first slipped over the lower end of the chamber A before the same is connected with the stand, and slides upon said chamber, and is attached thereto by the slotted arm f', depending from the circular body E2, and a set'screwj, passing through said slotted arm and entering the side of the chamber A. By this arrangement it will be seen that when the same is not in use it is readily lowered to the positionshown in dotted lines, Fig. l, and also readily elevated to the position for use, as shown in full lines in said figure, and held in place by adjusting the screw f2.

The platesj'of the regulator are slightly concaved and are bent inward, so that the upper ends ol` the said plates hug theedge of the upper openings, cl, and leave a space, di, in the lower openings, d', down through which the gas passes. After issuing from the passages cl2, the gas rises and burns mainly at the angles of and between the hollow' arms C C. In this manner a perfect combustion is secured and thejets of llame are confined to a small limit.

In place of the regulator Eplaced upon the chamber A, I may use a top regulator, F, (shown in Fig. 4,) to be applied by hand, the plates h thereof entering theupper openings, (l, and projecting down into the lower openings, d, and the said plates h diverging, so as to cut the gas ofi' from the upper openings, d, but leave the space d in the lower opening, thns'eflecting the same purpose as the regulator E.

Thejet-tube B is shown mounted upon a IOC small stand,G-,to which gas is supplied through a tube, G.

. Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. As a new and improved article of manufacture, a gas-stove comprising the chamber A, adapted to fit upon a gas-jet and having opening Z) near the top of the jet, the radial hollow arms O at the top of the said chamber, and the surrounding flange D, the said hollow arms C being formed with the corresponding openings, d d', at their upper and lower surfaces, substantially as described.

2. The combination, with the chamber A, adapted to t upon a gas-jet, and formed'at its upperv end with the hollow arms C, having e upper and lower corresponding apertures, d d,
